amazon.com multiple SPF records
by Brad Barnett 07 Jun '21

07 Jun '21

If anyone at Amazon is paying attention, you have duplicate spf1 records for amazon.com: # dig -t TXT amazon.com | grep spf amazon.com. 281 IN TXT "spf2.0/pra include:spf1.amazon.com include:spf2.amazon.com include:amazonses.com -all" amazon.com. 281 IN TXT "v=spf1 include: amazon.com include:spf1.amazon.com include:spf2.amazon.com include:amazonses.com -all" amazon.com. 281 IN TXT "v=spf1 include:spf1.amazon.com include:spf2.amazon.com include:amazonses.com -all" It's causing mail deliverability issues, so users cannot reset their password, or even get OTP codes reliably. (I don't know where else to post, as whois/arin contacts aren't responding, and I can't even imagine trying to go through other methods of support...)

OSI layer 1 and revisiting labelmakers in the year 2021
by Eric Kuhnke 07 Jun '21

07 Jun '21

I am still using a Dymo 4200 [1] which is generally okay. I am wondering if anyone or their field tech team has recently changed to a better label maker in terms of feature set, battery life/charging or label consumable cost. Surely there must be something better out there. Strong preference for QWERTY keyboards, no ABCDE type. [1]: https://www.dymo.com/en_CA/rhino-industrial-4200-qwy.html

We swear by the Brother P-touch EDGE PTE550W. It’s reasonably priced and offers an extensive feature set. In addition to the QWERTY keyboard the built in WiFi allows us to connect it to our laptops and/or smartphones to print out labels that we generate from Netbox.

Muni broadband sucks (was: New minimum speed for US broadband connections)

Personally I wouldn't mind more access to dark fiber à la Stokab, much like the dry copper pairs of yesterday. If the default state of muni broadband of is suck, what is the root cause? Is it a people problem and/or can something be done to improve on the default state? Jared

BGP38 egress filter on Ubuntu Server
by Stephen Satchell 02 Jun '21

Before I re-invent the wheel, has anyone come up with blackhole route specifications for netplan in Ubuntu servers? Such a capability would perform the egress blocking for an edge server. The table of blackhole routes I would set up: IPv4 Address block Scope Description 0.0.0.0/8 Software Current network (only valid as source address). 10.0.0.0/8 Private network Used for local communications within a private network. 100.64.0.0/10 Private network Shared address space[3] for communications between a service provider and its subscribers when using a carrier-grade NAT. 127.0.0.0/8 Host Used for loopback addresses to the local host. 169.254.0.0/16 Subnet Used for link-local addresses between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server. 172.16.0.0/12 Private network Used for local communications within a private network. 192.0.0.0/24 Private network IETF Protocol Assignments. 192.0.2.0/24 Documentation Assigned as TEST-NET-1, documentation and examples. 192.88.99.0/24 Internet Reserved.

Re: New minimum speed for US broadband connections

Does not need to be – just a suggestion based on the thinking that these locales may have more dense populations and thus perhaps higher FTTH penetration for a longer period of time. But the data from any network will certainly have some interest.

The last 5 yrs. have definitely changed the profile of a typical home user. A 4M upload pipe, will hit bottlenecks with all the collaboration that is happening remotely. I'm not sure ratio is the right thing to focus upon - especially as asymmetry has grown the last few years due to the rising using of streaming video services and greater availability of 4K-resolution content. Ratio seems like more a reflection of current applications and usage patterns. (It would be fascinating to see a non-US FTTH provider that was 1G/1G or greater share their actual usage ratio.) JL
